list1 = [{'agent': 0, 'loc': (1, 2), 'timestep': 1}, {'agent': 1, 'loc': (1, 3), 'timestep': 2}]
我有这样的字典列表，我想附加10个与原始列表的最后一个元素相同的项目，并将每个时间步的值增加1，以新附加的元素结束，使时间步按升序增加1.我try 像下面这样迭代，但最终将所有时间戳值都增加到了一个很大的数字.
for i in range(10):
list1.append(constraints[-1])
list1[-1]['timestep'] +=1
非常感谢您的帮助
try 添加.copy():
list1 = [
{"agent": 0, "loc": (1, 2), "timestep": 1},
{"agent": 1, "loc": (1, 3), "timestep": 2},
]
for i in range(10):
list1.append(list1[-1].copy())
list1[-1]["timestep"] += 1
print(list1)
打印:
[
{"agent": 0, "loc": (1, 2), "timestep": 1},
{"agent": 1, "loc": (1, 3), "timestep": 2},
{"agent": 1, "loc": (1, 3), "timestep": 3},
{"agent": 1, "loc": (1, 3), "timestep": 4},
{"agent": 1, "loc": (1, 3), "timestep": 5},
{"agent": 1, "loc": (1, 3), "timestep": 6},
{"agent": 1, "loc": (1, 3), "timestep": 7},
{"agent": 1, "loc": (1, 3), "timestep": 8},
{"agent": 1, "loc": (1, 3), "timestep": 9},
{"agent": 1, "loc": (1, 3), "timestep": 10},
{"agent": 1, "loc": (1, 3), "timestep": 11},
{"agent": 1, "loc": (1, 3), "timestep": 12},
